Vehicle-to-vehicle and vehicle-to-infrastructure communications made possible by IntelliDrive will enable new transportation applications and services. To understand and quantify potential benefits from IntelliDrive applications, these applications should be evaluated before field deployment. An IntelliDrive simulation environment was developed; it replicated precise vehicular movements, incorporated IntelliDrive wireless communications based on wireless access in vehicular environments–dedicated short-range communication standards, and simulated real IntelliDrive message sets defined in the Society of Automotive Engineers J2735 standard. A case study of a prototype lane changing advisory algorithm revealed that communication delays were not likely to be a significant factor and showed maximum delays of only 55 ms for the basic safety message (BSM) and 1.3 ms for the a la carte message (ACM). The probability of successful communication can affect evaluation results. For example, for a lane changing advisory algorithm, the probability of successful transmission of a series of required messages—three BSMs and one ACM—was only 50% when fewer than 120 vehicles were within a communication radius of 50 m. This result implied a significant degradation in algorithm performance. The results demonstrate the feasibility of integrating traffic and communication simulation models and the need to consider both components in IntelliDrive evaluation.
